Our electricity storage units.
As sustainable as the energy they store.
Technology
As sustainable as the energy they store.
Our metal-free Redox Flow battery (also called a “flow battery”) is as innovative as it is environmentally friendly. Being a freely scalable storage system, it is the future-oriented alternative to conventional lithium-ion accumulators and metal-containing redox flow electricity storage devices. And a real contribution to the energy transition.
Why is it called Redox Flow?
Redox Flow electricity storage units are environmentally-friendly electrochemical energy storage systems.
In this respect, “Redox Flow” is an abbreviation of:
Reduction = Uptake of electrons
Oxidation = Output of electrons
Flow = A liquid storage medium
Technology
Sustainable storage
This is how it works
Two tanks contain a salt solution with various organic (metal-free) storage substances for the positive and negative poles. The salt solution is pumped through a cell to charge and discharge it. In this way, electrons are bound and released again - and electricity is stored.
The result: The accumulator’s power and capacity can be scaled independently of each other. The amount of electrolyte defines the capacity of the flow battery, and the area and number of cells define its power.
